Sass ruled for a decade, then CSS absorbed its best features. The honest 2026 picture:
What native CSS took over
/* variables — native and BETTER (runtime, themeable) */
:root { --brand: #6d6ffb; }
/* nesting — native now! */
.card {
padding: 16px;
&:hover { transform: translateY(-2px); }
.title { font-weight: 700; }
}
/* math */ width: calc(100% - 2rem);What Sass still does uniquely
@mixin flex-center { display: flex; justify-content: center; align-items: center; }
.hero { @include flex-center; }
@each $name, $color in (success: green, danger: red) {
.btn-#{$name} { background: $color; }
}
/* partials: _buttons.scss, _cards.scss compiled into one file */The verdict
- Learning today: master modern CSS first — variables, nesting, functions cover 80% of why Sass existed
- Job reality: tons of existing codebases use SCSS — reading it takes an hour to learn, so don't fear it in job posts
- New projects increasingly choose plain CSS or Tailwind over Sass
